CHESTER F. JOHNSON, F DETROIT, MICHIGAN.

HOOD FOR MOTOR-VEHICLES.

To all whom tt-may concern: i

Be it known that I, CHESTER F. J oHNson, a citizen of the United States, and a residentof Detroit, in the county of lWayne and State of Michigan, have invented a new and Improved Hood for Motor-Vehicles, of which the following is a specification.

The louvers o r `heat escape openings in the Walls of the hoods for automobile radiators are commonly closed in cold weather by exterior jackets or coverings that surround the entire hood; and it has also been proposed to line the inside of the hood with heat insulating material cemented or riveted in place. The former construction is expensive and unsightly; the'latter, if tight enough to retain the heat during cold weather, would not allow suicient air'circulation` in the summer.

` The present invention possesses the advantages of each of the above constructions and avoids the objectional features thereof.

It consists, in combination with a hood arranged to allow circulation of air during hot weather, of a closure carried in the interior of the hood and adapted to be positioned across the air opening or openings to prevent air. circulation at will.

The invention further consists in the details of construction shown, described and particularly pointed out in the subjoined claims. v Y

In the drawings, Figure l. is a side view ofthefront endof a motor vehicle, parts being broken 'away and the engine being vomitted to show the construction of thc hood. lI" ig. 2 is a section of the near side of the hood on the line 2-2 of Fig. 1. Fig. 3 is-a similar enlargedv fragmentary section on the line 3-3 ofFig. 1. Fig. 4 isan enlarged fragmentary section on the line 2 2 of Fig. 1.

" Similar reference characters refer to like parts throughout the several views. l

, In the `embodiment of my invention shown, the upper sections 1 and 2 of the hood are joined by the longitudinal pivot 3 that allows either section to be swung upwardly about the edge of the other; and to the edges ofthe upper sections the side sections 4 and 5 are attached by the longitudinal pivot rods 6 and 7, the latter allowing inward swinging movement of the side sections about the edges of the upper sections. The hoodmay be supported'atits front end Specification of Letters Patent.

manner. The general construction thus far` described is well known.

The usual longitudinal side bars are indil cated at In this instance they are, however, provided with a dust guard 16 that is secured to their upper flanges and projects outwardly therefrom, and with a hood shelf.

having a horizontal flange 17 and ar vertical flange 18 disposed along its inner edge. It will be understood that the openingfbetween the side bars is closed in the usual way (not shown). When the hood is in position, the lower edge is s aced somewhat from the hood shelf, to agord, as best shown on the left side of Fig. 2, a passage 20 through which the heated air may escape inthe manner indicated by the arrow. This passage, it will be noted, is supplemental to the usual louvers 21. The hood maybe clamped down by the spring clamps 22 that engage with bracket hooks 23 in a well known manner.

. The pivots between the side and top sec tlons may be formed in various Ways, but ay preferred construction will nowv be described :-The lower edges of the top sections are bent back parallel to 'andspa'ced from the body portion at 28 to allow the insertion of one end 29 of a hinge clip, the mid-portion of which passes aroundthe corresponding pivot rod 6 or 7, its other end 30 being brought down along the inside of the portion 28. These partsv are then secured together by the rivets 31. The side sections 4v and 5 are of single thickness throughout the major portion of their length and may be provided near their ends with reinforcing strips 32 (but one of which is shown). As best indicated in Figs. 3- and 4, the side sections are bent inwardly near their upper edges to form offsets 33 that terminate in the vertical edge portions 84. The latter are embraced at points longitudinally adjacent the clips 29-30 by similar clips 85 that may be secured thereto by the rivets 86 and embrace the pivot rod. At the end portions these rivets may also serve to secure the reinforcing strips 32 in position. It will be seen that water dripping from the upper sections is discharged without coming in contact with the hinge members. Also mounted to swing vertically on the pivot rods 6 and 7 are the closures 38, the edges of which nearest the hinges are provided at'intervals with the hinge portions 39 that inclose the corresponding pivot rod. It is desirable that the number of hinge portions 39 be equal tothe number of the hinge clips of each-set heretofore described, thus allowing the three hinge elements to.V be arranged in series, as indicated in Fig.- 1. The closures may occupy either the open position indicated at the left side of Fig. 2 or the closed position shown at the right, and when in open position, may be retained by the rivets or bolts 41 and wing nuts 42. In order to clear the parts in the vicinity of the pivot when in'closed position, the upper portion of the closures may be oiset inwardly at 43; and its lower edge may be flanged at 4:4 and provided with the longitudinal strip 45 secured thereto by the rivets 46 and spaced therefrom to receive the felt strip 17. The inner edge of this strip isl adapted to contact with the flange 1S of the hood shelf to form a seal, and when in open position cngages with the lower side of the hood, I

,whereby rattling is avoided.

lIn warm weather the closures are supported by the bolts il; when, however, it becomes desirable to prevent the circulation of air, half of the hood is swung upwardly about the pivot and the nut 42 is unscrewed'to release the corresponding closure, after which the latter swings downwardly parallel to the side section. The closure and side section are then lowered outside of the flange 18 andare secured in position by the clamps 22 that hold the felt in tight engagement with the flange. This not onlyl seals the supplementary air passage but also prevents rattling. Since the closure is entirely within the hood, the latter may be given the usual graceful lines and glossy finish, its appearance being thesame in winter as in summer, and being una'ected in any manner by the presence of the closure.

j.'v It is clear that many changes may be.l made in the details of the construction without wise than as indicated by the subjoined claims. f l.
